tips of repair a laptop battery
Author: udtekadapter
Author: udtekadapterThe first laptop I ever owned was a hp dv6000 and the hp pavilion dv6000 battery was down to 20 minutes life after about a month. I yelled about it at hp until they sent me a new laptop battery, which was stone dead within a few weeks. Laptop batteries from some manufacturers have notoriously short lifespans (not mentioning any names here:-), and the Ni-MH (Nickel Metal Hydride Battery) which replaced NiCd (Nickel Cadmium) in most applications just arent that much better. So, I thought Id crack open the stone dead battery back and see if it could be rebuilt. The first thing I learned is that laptop battery packs arent built to be rebuilt, they GLUE the things closed. Took some serious prying to get the thing battery pack open, but definitely in reusable condition.
Share: HP/Compaq Pavilion DV6000 Battery 12-cells 8800MAH Description:

UL certificated cells inside! There isnt a whole lot to a laptop battery, just a hard plastic shell, enough individual cells to make up the required voltage, and a thermocouple. The black wire scotch-taped between two battery cells is the thermocouple, and its positioned to measure the air temperature in the battery pack, not the actual battery surface temperature. Maybe thats why the batteries fail so fast. The only other component in the battery pack is the little circuit board (below), which has nothing on it but the contacts for the notebook DC circuitry. Looking at it from the outside, you would have thought there was some fancy charging circuit inside, not so. When you buy a replacement laptop battery cheaply at udtek.com , youre just getting a new set of cells to run down. The individual cells that make up the laptop batteryare simply strapped together with little contact strips which are soldered in place (below). To repair a laptop battery, you need to replace all the cells and resolder, but heres the problem. thats the first one that came up in Google. To cost effectively repair a laptop battery, youd either need to find the replacement cells wholesale, or be doing it for a laptop whose battery is just ridiculously overpriced to start with. Live and learn.I searched around for a price on the cells at udtek.com, you only spend $76.99 to replace the dv6000 battery.About the Author:
